CONTAINER Filed April 23, 1936 INVEN BY uw S Patented Nov. 23, 1937 STATES PATENT OFFICE laim.

This invention relates to the cylindrical container for the packaging and mailing of merchandise or the like and the method of .manu facturing the same.

' The objects of the invention are:

First, to provide a container of combined paper and metal which is substantially sealed, which is very strongand simple, and produced without the use of rivets or other similar attaching devices.

Second, to produce such a structure in which the crimping of the paper wall upon the metal will serve as an effective fastening means for the endclosures of such a receptacle.

Third, to provide an improved process and means for the manufacture of such a container.

Further objects pertaining to details will appear from the description to follow. I accomplish the Objects of my invention by the devices and means illustrated in the accompanying draw-- ing, in which: a i

Fig. 1 is a longitudinal axial section through a cylindrical container embodying-my invention.

Fig. 2 is a detail view of the method of pro-,

ducing the cylindrical wall of the container.

Fig. 3 is a detail vertical sectional view of the machine or apparatus for crimping the ends of the cylinder walls onto the metallic heads or ends of the container.

Fig. 4 is an inverted plan view looking at the face of the crimping head.

Fig. 5 is an enlarged detail sectional view on line 5-5 of Fig. 4, showing the detail of the bottom of the groove. v

I Fig. 6 is an enlarged sectional detail showing the method ofaction of the spinning crimper head in crimping ends of the container bottom.

The parts will be identified by their numerals of reference which are the same in all the viewsr l is the cylindrical body of the container. 2 are the sheet metal heads therefor of stamping with out-turned flanges 3. The walls of the body I are made up of a central portion 4 of spirally wound cheap paper tube, preferably made of quite heavy material and cut 011 square at the ends to form the shoulders for receiving the heads 2 of the container. An outer layer 5 is made up by wrapping a firm high quality of paper, kraft or otherwise, around the tube as seen in Fig. 2, forming the shoulders 6 against which the metallic heads 2 rest. This makes the outer covering of the wall of one or more plies of paper. After the container has been filled or the article desired .to be shipped in it has been introduced, it is closed by inserting the head 2 against the shoulder 6 and subjecting the projecting edge of the outer layer 5 to the action of a crimping machine which is made up preferably of a head containing concentric grooves succes- 5 sively of the diameter to correspond to the particular package to be closed.

This is seen in a preferred form in Fig. 3 in which the spinning head i is driven by an electric motor 8 being directly mounted on the arbor 9 thereof. The whole machine is supported on a suitable base ill with a standard ll flanged at l2 to receive the motor 8. The head i is provided with concentric grooves l3 in the bottom of each groove, there being a projection I! which 15 spreadsput the laminated layer 5 and crlmps it over the flanged edge 3 of the metallic head 2. In the preferred form this head 2. is supported by the shoulder 6.

I provide a table IS on rack plunger l6 oper- 20 ated by pinion and crank. The packages should be held by the hand in this operation. Only one groove is needed for each size. A

The revolving plate may be provided with a crank for its operation and the Package may be 25 held in the hand against the revolving plate with- I out other support and do an efiective job 01' transparent and the head could be formed in a 35 variety of ways with the flange in position to receive the crimped edge. I desire to claim the same as metallic and also to claim the same broadly.

Having thus described my invention, what I 40 claim as new and desire .to secure by Letters Patent is:

A mailing tube or package comprising an inner body of spirally wound low grade paper tube, an outer layer of kraft paper wrapped 45 thereon in concentric layers and projecting beyond the end of the spiral tube to form shoulders, and flanged heads for said container bottomed against the ends of .the inner tube with the projecting ends of the kraft paper layer bent 50 and crimped over the flanges of the heads, whereby the heads are retained in place. by the folding and crimping of the kraft paper.
